T0 @ZZ whom, it may concern:

fggxBe it known that I, IIEURADIAS GRANT SIMPSON, a citizen of the United States, and a resident of Elkhorn, in the county of llic- Dowell and State of I,West Virginia, have made an Improvement in I-Iorse-Detachers, of which the following is a speciiication. ,im My invention is an improved attachment for the frontaxles of carriages and wagons for releasing poles and shafts in case of danger from a horse or team running away.

It is more particularly an improvement in that special class of detachers which include sliding bolts adapted to secure pole or shaft irons, and a vertical oscillating lever with which such sliding bolts are connected by links or rods.

The details of construction, arrangement, and operation of parts are as hereinafter described, and illustrated in accompanying drawing, in which Figure 1 is in part a section and in part a front view of my improved attachment in one ofits forms. Fig. 2 is a plan view of the same. Fig. 3 is a vertical section on the line 3 3 of Fig. 1. Fig. 4 is a plan v iew illustrating a modification. Fig. 5 is a plan view illustrating separate from the axle the attachment shown in Fig. 4. Fig. 6 is a front view of the attachment shown in Figs. 4 and 5 with a modified arrangement of the springs.

The' frame of my improved attachment com rises a bar A, arranged in rear of and para lel to the front axle of a vehicle, and four arms or short bars B B, which are rigidly secured to the rear bar A and extend forward therefrom at right angles and are in the same--to wit, horizontal-plane, also a bar C, which is arranged between and connects the arms or bars B and is arranged in front of the axle. As shown, the arms or bars B B are arranged in pairs at the ends of the rear bar A and are duly spaced apart. The outer arms' B are provided with slots b at their outer ends to receive the irons D of poles or shafts, and rods or bolts E are arranged to engage the same, as will be readily understood. The bolts E are made of such length as to extend through the two arms of each pair, and their inner ends are connected with a vertical pivoted lever F by means of links or jointed rods G. -A spiral spring I-I is applied to each rod E between the bars B B, the inner end of said spring bearing against the inner bar B and a collar h fixed on the sliding rod E near its opposite end. It is apparent that the function of the springs is to hold the sliding rods E normally extended or in locking engagement with the pole or shaft irons l), and that the rods E can be retracted only by operation of the lever F. rPhe latter is pivoted to the center of the frame-bar C and is provided with a slot through which passes an arc-bar I, as shown in F ig. 3. The said arc-bar is arranged vertically' and bolted to the face of the frame-bar C, as shown in Figs. l and 2. The arc-bar I is rovided in its upper edge near its center wit a notch i, that receives a locking bolt or pawlf, forming an attachment of the lever F. The said bolt f is operated-that is to say, withdrawn from engagement with the arcbar-by means of a rod and lever f f2, whose arrangement and operation are obvious from inspection of It will be seen that when the lever F is placed in the vertical position indicated by full lines, Fig. l, and locked by the bolt the sliding bolts E are secured so that accidental release of the pawls or shafts is impossible, and that upon raising the bolt f the lever F may be thrown to the left, as indicated by dotted lines, whereby the tension of the springs Il will be overcome and the bolts E withdrawn, thus releasing the team. The apparatus is thus characterized by the utmost security when in use and by ease of operation when it is required to detach the poles or shafts. The invention is very useful for detachment o f poles andv shafts when it is required to store or ship a carriage or wagon in the least space practicable.

It will be understood that since the front axle passes through and has its bearings in the frame-bars B B the frame as a whole is practically balanced on the axle, and the hand-l ever F is sup ported in vertical position just in front of and parallel to the dashboard or other front of the vehicle-body, so that it may be readily seized and operated by the driver. I do not desire to limit myself to a special method or means of attaching the frame to the axle, since I contemplate effecting this in diil'erent ways, according to conditions, so that the frame may be applied to axles of carriages or wagons already in use, as well as to those in process of construction.

In Fig. 4 Iv show a modification of the frame, the bar A being rigidly connected with two arms B2, the inner arms B before described, being dispensed with. The bar IOO IIO

A depends from the arms B2, and is thus adapted to iit behind the axle parallel thereto and in contact therewith. The bar is secured to the axle by means of clips of any preferred construction. The outer ends of arms B2 are connected by parallel bars C', and the arc-bar I, with other devices, constituting the locking and releasing mechanism,- are arranged on or in connection with these bars. The sliding bolts are arranged in blocks secured between the two bars, as shown. Fig. 5 shows this modified attachment separate or detached from the axle, and in place of shafts D', being attached as shown in Fig. 4, swingletrees are'attached in their place as required when the team is double, a pole or tongue (indicated by dotted lines) being also suitably connected with the frame attachment.

In Fig. 6 l illustrate a front view of the attachment shown in Figs. 4 and 5, save that in place of the springs E being arranged as before they are connected at one end directly with the lever F2 at points aboveand below the )ivot and at their opposite ends with the arcar or other adjacent vfixed portion.

It will be seen that by the construction, combination, and arrangement of parts before described I provide an attachment foar the front axle of vehicles and wagons which i includes detaching mechanism for both swingle and double trees, and that the frame constituting the body of such attachment may be readily secured to or detached from the axle.

What I claim isl. The improved attachment for vehicles comprising a frame which includes a rear bar, arms projecting forward therefrom and adapted to extend in front of the axle, a front bar connecting the ends of said arms, sliding bolts for engaging shaft-irons or swingletrees, connecting-rods, springs and pivoted lever arranged vertical for operating such sliding rod, substantially as described.

2. The attachment for the purpose specified, comprising a rear bar adapted to engage the 'front axle, parallel horizontal arms extending forward from the ends of said bar7 two parallel bars connecting the front ends of said arms, sliding bolts arranged between the bars and in suitable bearings or supports, a lever pivoted between the bars and adapted to swing in a vertical plane, links connecting the lever with the aforesai'dbolts, and springs applied to the bolts, substantially as described.

3. The'combination with a front axle of a vehicle, of an attachment comprising a bar adapted to engage the rear side of the axle, arms extending forward horizontally from the axle from the ends of said bar, a front bar which rigidly connects the front ends of said arms, the latter having slots for receiving thill-irons or swingletree-eyes, bolts'sliding in guides on said bar for locking or releasing horseV attachments, a lever arranged? vertically and pivoted to thefront bar and with which the inner ends of the bolts are connected, an arc-bar, and means for locking the lever therewith, and springsapplied for holding the bolts normally extended andlocled with the horseattachments, substantially as described.
